Question

Canvas

Answer 1

assuming you have a canvas tag assigned an id to it:

In JS:

var canvas = document.getElementById("your ID");
var context = canvas.getContext("2d");

//now to draw the arc

context.strokeStyle = "blue";

context.beginPath();
context.arc(50,50,20,0,2*Math.pi);
context.stroke();
context.fill();

Drawing an outline of a circle you use stroke.

Drawing a filled circle you use fill
